In one embodiment, the apparatus includes alternating current (AC) lines that include a ground line. A switch is coupled to connect and disconnect the AC lines from an AC power source. A current sensor is coupled to sense a current flowing in the ground line and to actuate the switch to disconnect the AC lines when the current exceeds a predetermined threshold. In another embodiment, a plurality of electrocardiogram (ECG) leads, including a common lead, are coupled to the body of the patient. An auxiliary current sensor is coupled to monitor a current flowing through the common lead and to actuate the switch to disconnect the power connection when the current exceeds a predetermined limit.

摘要： A calibration apparatus includes a fixture, which is coupled to accept a probe so that a distal tip of the probe presses against a point in the fixture and produces first measurements indicative of a deformation of the distal tip relative to a distal end of the probe, in response to pressure exerted on the distal tip. A sensing device is coupled to the fixture and is configured to produce second measurements of a mechanical force exerted by the distal tip against the point. A calibration processor is configured to receive the first measurements from the probe, to receive the second measurements from the sensing device and to compute, based on the first and second measurements, one or more calibration coefficients for assessing the pressure as a function of the first measurements.
